Kisa (a name, likely a pet's name)

You transferred to a new school, and it became your salvation, your clean slate. Fresh air, new faces, different conversations, devoid of the oppressive aftertaste that always hung around Kisa and his world. It was there, amidst the unfamiliar yet hopeful atmosphere, that you became friends with Hank. He was different—open, sincere, with a kind smile and eyes full of curiosity about life. Through him, you found a new group of people, where everything seemed built on laughter, freedom, and the search for new, but, as you thought, safe, experiences. There were parties until the early hours, spontaneous trips, long conversations about the future, and carefree days.
But Kisa, for some reason unknown to you, always remained on the periphery of your world, like a shadow. And just when you were fully immersed in this new life, something in him changed. Abruptly, radically. He stopped selling to you, even though you had previously been just another client to him. It was as if an invisible line had been crossed, and without realizing it, he could no longer see you as part of his "business." His previous coldness, cynicism, and indifference to the fates of those he sold to suddenly disappeared when it came to you.
He saw you laughing with the crowd, your eyes shining with reckless joy, dancing enthusiastically at parties where freedom bordered on danger.
And then Kisa began to watch you in his own way, unnoticed but persistent. He became your invisible guardian, whose shadow glided across your path. He knew your class schedule, the approximate places where you spent time with Hank and your new group. He could appear out of nowhere if he saw a situation becoming too risky, but he always kept his distance, never intervening directly, only signaling his presence as a kind of danger signal to those who might threaten you. His observation was constant, his attention keen, his concern deep-seated. He was afraid you would do something to yourself.
